Title: Interchangeable static and isodromic speed governing for prime movers
IPC: G05D13/00
Filed: 1932-12-05
Abstract: 402,935. Speed governors. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Dec. 5, 1932, No. 34459. Convention date, Dec. 11, 1931. [Class 57.] A speed governing system may be used as a system wherein a degree of irregularity is present, static governing, or wherein when a variation in speed occurs, the speed is returned to its original value after a governing action, isodromic governing. Fig. 1 shows a governor 2 controlling a valve 1 through a control valve 4 and power cylinder 3. A motor 19 engages the sleeve 5 which is connected through links and a spring buffer 10 to the link 27. The rod 14 is in threaded engagement with the sleeve 13 and the rod 12 slides within the sleeve 13 but may be clamped in any position by the screw 20. For static governing the screw 20 is released and the rod 12 slides idly within the sleeve 13. The motor 19 is employed for adjusting the sleeve 5 according to the load which the machine is required to take. For isodromic governing, the screw 20 is engaged and the resistance starter 29 put in the circuit of motor 19. When a governing action occurs movement of the rod 9 so controls the motor 19 that the sleeve 5 is moved in a direction that in the return movement, the valve 4 has to travel further to centre the ports. The motor 16 is employed for varying the speed at which the governor shall act. In a modification the sleeve 5 is secured to a spindle actuated by one motor and two screw 4 clutches are provided, one being engaged for static governing and the other for isodromic governing. Fig. 3 shows the spring buffer replaced by a valve 58 and sleeve 59 which during static governing causes the motor 16 to operate to cause the sleeve 59 to follow the valve 58. During isodromic governing the valve 58 controls the motor 19 and the motor 16 then functions as a speed adjustment. In a modification the valve 58 is mounted upon an extension of the governor sleeve. A further modification shows the electric motors replaced by hydraulic motors. Fig. 6 shows the governing systems applied to a fluid governor wherein a pump 108 is driven by the prime mover and a part of the stream flows through the " quantity " valve 113 and the remainder past the throttle valve 110, the united streams passing to the " pressure " valve 116. During static running the speed adjustment is made by the motor 126 and the pilot valve 127 actuates the motor 129 to cause the sleeve 128 to follow movements of the valve 127 due to movements of the valve 116 to maintain constant pressure in the space 114. For isodromic governing the pilot valve controls the motor 126 to cause a slight adjustment so shat the speed of the prime mover shall be the same after the action as before. Speed adjustment is then carried out by the motor 129.

Title: Improvements in the treatment of gases containing hydrogen and unsaturated hydrocarbons
IPC: C01B3/56
Filed: 1928-11-26
Abstract: 325,309. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 26, 1928. Unsaturated hydrocarbons are separated from gas mixtures containing them in admixture with hydrogen, which mixture has been obtained by the thermal treatment of gases containing hydrocarbons, by adsorbing the unsaturated hydrocarbons from the said mixture, while working under pressure and using solid adsorbents. The operation may be carried out while cooling. In an example, a gas obtained in the destructive hydrogenation of coal is treated in the electric arc, and the gas mixture so produced, containing 8 per cent of acetylene, is passed under a pressure of 20 atmospheres through active charcoal. The residual gas is substantially free from unsaturated hydrocarbons, and may be used, if desired, under its existing pressure, for hydrogenation purposes.

Abstract: 932,098. Packaging machines. SAPAL, SOC. ANON. DES PLIEUSES AUTOMATIQUES. Sept. 28, 1961 [Dec. 21, 1960], No. 34864/61. Class 94(1). A device deposits single articles in individual compartments of a container moved in a straight line several depositing stations at a uniform speed. Containers 12 are moved by conveyer 10 beneath stations 1, 2, 3 &c. having rotary discs 4, 5, 6 &c. carrying articles 7, 8, 9 &c. in hollows. Each disc is carried above a fixed disc 13, Fig. 2, on a shaft 14 rotated by a disc 15 and pins 16 driven intermittently from the conveyer drive so that the speed of the article is the same during depositing as that of containers 12. A further shaft 17 carries arm 18 and suction cup 20 and is raised and lowered and reciprocated rotationally synchronisally with the conveyer drive means. At the depositing stage, arm 18 rotates with the disc 4, 5, 6 &c. and moves down so that suction cup 20 grips an article; the arm 18 then moves down to pass the article through an opening in disc 13 into container 12. The vacuum is then released and arm 18 moved upwardly and rearwardly. The discs 4, 5, 6 &c. may be changed to accommodate different shaped articles. The stations may be moved perpendicularly to the conveyer 11 to fill any desired row of the containers. Several small articles may be deposited in each compartment.

Title: Improvements relating to inertia motors and devices operated thereby
IPC: G09F21/04
Filed: 1934-12-06
Abstract: 448,442. Utilizing inertia; escapements. HUMPHREYS, J. N. C., Salisbury House, London Wall, London. Dec. 6, 1934, No. 35078. [Class 80 (iv)] [See also Groups XVIII and XXVI] An inertia motor comprises two masses 4, 9 each acting through a pawl 8, 10 on a ratchet wheel 7 which gradually winds up a spiral spring, the stored energy in which is released at intervals to rotate a surrounding casing 1 through a predetermined angle. The mass 4 is carried on arms 6 swinging loosely -on a fixed shaft 2, spiral springs 5 forming a resilient connecting link between the arms 6 and the shaft 2 to support the mass 4 floatingly in a position which will cause it to impart rotation to the wheel 7 with vertical vibration of a base 3. The mass 9 hangs loosely from the shaft 2 in the form of a pendulum 11, and imparts rotation to the wheel 7 with sideways vibration of the base 3. Each pawl 8, 10 acts as a detent for the other. The casing 1 is provided on the inner side of each face with a finger 15 held outward by a spring 17 and adapted to hold the casing in fixed position against the action of the storage spring by abutting against a stop 16 fixed on the shaft 2. The finger 15 is pressed back to allow it to pass the stop 16 by a pin 24 carried on a toothed wheel 20 gearing with a wheel 19 fixed to the ratchet 7, the wheels 19, 20 being dimensioned with a relation depending on the number of sides to the casing 1. The casing 1 carries a pawl which engages a ratchet wheel fixed on the shaft 2 to prevent back motion of the casing under the pressure of the pin 24 on the finger 15. The storage spring is attached at one end to the casing 1 and at the other to a member which forms part of a friction clutch between the spring and the wheel 7. A spring buffer may be introduced between the masses 4 and 9 and the ratchet mechanism. The casing 1 may form a display sign.

Abstract: 939,746. Transfer devices for conveyers. E. HABICHT, and G. MEINAS. Sept. 29, 1961, No. 35125/61. Class 78 (1).  Containers are delivered to work places next to a conveyer and are retained for a manuallycontrolled period before being returned on a lower conveyer. Table A is electromagnetically tipped to slide a container B off the upper conveyer, a cord attached to platform A releasing a catch 3 to enable a platform 2 to tilt about pivots 6 under the action of a spring 5 to receive the container B. The weight of container B on platform 2 acting about pivots 6 which are off-set from centre returns platform 2 to the horizontal position and re-engages catch 3. At the same time pin 8 (see Fig. 7) is depressed to release a catch 11 which permits a holding platform 12 to tilt under the action of a spring 13 (see Fig. 8) about pivots 14. The tilting of platform 12 operates a lever 18 to which a cord 19 is attached, thus releasing a catch 20 holding platform 2 from tilting about pivots 21 (the axis of these pivots is perpendicular to that of the pivots 6, Fig. 1) so that the container B slides from platform 2 down to platform 12, where the weight of the container B causes platform 12 to resume the horizontal position, as does platform 2 under the action of spring 5, both catches 11 and 20 being re-set in the process. The container B is held on platform 12 while required at the working station and is released to the return conveyer by a manual switch 30 which enables platform 12 to tilt about pivots 33 (the axis of which is perpendicular to the axis 14, Fig. 8), a platform E receiving the container in much the same way as the container B is transferred from platform 2 to platform 12 and lowers the container B on to the return conveyer.
